🚀 Day 7 of My Python Learning Journey – Tuples in Python

🔹 What are Tuples?
• Tuples are ordered and immutable collections.
• They can store multiple items like lists, but unlike lists, they cannot be modified (no append, remove, etc.).
• Defined using parentheses ().

fruits = ("apple", "banana", "cherry")
print(fruits[0]) # apple

🔹 Key Properties of Tuples

✅ Ordered → items have a fixed sequence
✅ Immutable → can’t change once created
✅ Allow duplicates → can store repeated values
✅ Can store mixed data types

🔹 Why Use Tuples?
• Safer than lists if data shouldn’t change
• Faster than lists (performance benefit)
• Can be used as dictionary keys (since immutable)

🔑 Tuple Operations & Examples

Accessing Elements

numbers = (10, 20, 30, 40)
print(numbers[1]) # 20

Tuple Packing & Unpacking

person = ("Alice", 25, "Engineer")
name, age, profession = person
print(name) # Alice

Concatenation & Repetition

t1 = (1, 2)
t2 = (3, 4)
print(t1 + t2) # (1, 2, 3, 4)
print(t1 * 2) # (1, 2, 1, 2)

Nesting Tuples

nested = (1, (2, 3), (4, 5))
print(nested[1][1]) # 3

🎯 Reflection

Tuples may look similar to lists, but their immutability makes them useful in situations where data must remain constant.
